VeganPizza69 ⓋⒶ<p>Relative environmental footprint from GWP100, land use, water use, eutrophication potential and biodiversity impact of diet groups in comparison to high meat-eaters (&gt;100 g per day).</p><p>"For measures of <a href="https://veganism.social/tags/GHG" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GHG</span></a> emissions, land use, water use, eutrophication and <a href="https://veganism.social/tags/biodiversity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>biodiversity</span></a>, the level of impact is strongly associated with the amount of <a href="https://veganism.social/tags/animal" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>animal</span></a>-based products that are consumed.

Paul Peace<p>Without the pet food industry providing a depository for meat waste, the price would rise and the pollution would be concentrated and obvious, instead of spread over large areas in dog &amp; cat poo.

Paul Peace<p>Instead of animal poo on farms, some farmers use only plants - green manures. These do not leach nutrients in the rain like muck-spreading and fertilisers.
